ARTHUR A. CHISHOLM AND ARTHUR- E. JAMES, OF BOSTON, MASSACHUSETTS.

DEVICE FR CHALKING CUE-TIPS.

Application led October 6, 1911.

Specification of Letters Patent.

To all whom it may concern:

Be it known that we, ARTHUR A. CHIS- I-IOLM and ARTHUR E. JAMES, subjects of King Greorge V of Great Britain, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Devices for Chalking Cue-Tips, of which the following is a specification.

This invention relates to improvements in devices for chalking the tips of cues, such as are used in playing billiards or pool. 1t is customary for the player to frequently apply chalk to t-he leather tip of his cue in order to prevent the same from slipping on the surface of the ball. To do this, a block of chalk with a hemispherical depression therein is utilized. The tip of the cue is placed within this hemispherical depression and the block of chalk rotated by the player to apply the chalk to said tip. The objection to this method of chalking 'a cue tip is that it is slow and the dust from the chalk gets on the hand of the player and onto his clothing.

The object of this invention is to provide a holder for a-block of chalk which is so supported upon a suitable casing that a player can introduce the tip of the cue in said hemispherical depression in the chalk, and by pushing upon the cue cause the chalk to rotate upon the leather tip of the "cue, t-hus applying the chalk thereto without the player having occasion to touch the chalk with his hands. A

The object of the invention is further to provide a device of the character set forth which is neat in appearance and which can be affixed to the wall at various heights and tipped at various angles so that the same may be used either in a horizontal or in an inclined position, according to the height at which the bracket supporting the device is placed above the ioor.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a side elevation partly broken away and shown in section of our improved device for chalking cue tips. Fig. 2 is a front end elevation viewed in the direction of the arrow a, Fig. 1. Fig. 3 is a sectional view taken on line 3-3 of Fig. 1. Fig. 4 is a transverse section taken on line 4 4 of Fig.

1 showing a cylindrical block of chalk within the holder. Fig. 5 is a transverse sectiontaken on line 4 4 of Fig. 1, showing a cubical blockof chalk in the holder. Fig. 6 is a detail side elevation of the guide cap and stop.

Like numerals refer to like parts through out the several views of the drawings.

In the drawings, 8 is a chalk holder oonsisting of a cylindrical member provided with a chamber 9 to receive a block of chalk. This block of chalk may be either a cylindrical piece of chalk 10, as illustrated in Fig. 4, or a cubical piece of chalk 10 such as is illustrated in Fig. 5. 'l

The block of chalk 10 has a hemispherical depression 11 therein and is prevented from `rotating in the holder 8 by prongs 12, 12

projecting into the bottom of the block of chalk 10, said prongs being fast to a strip 13, preferably of metal, which extends across the bottom of the block of chalk, as shown particularly in Fig. 1, said strip thence extending from the bottom of the block of chalk to the outer end thereof and lying in a groove 14 in the inner face of the wall of the holder S. of the holder the strip 13 is again turned at an angle at 15 by means of which the piece of chalk when worn down can be removed from the holder. Thus, the metal strip serves a twosfold purpose: One is to prevent the chalk from rotating in the holder, the other is to remove the chalk from the holder.

The holder 8 is rotatably mounted in a hollow cylindrical casing 16, and within this casing is located a spring 17, one end of which bears against the closed end of the casing 16, the other end thereof bearing against a washer 18 which, in turn, bears against the inner end of the holder 8.

A pin 19 (Fig. 4) projects into a helical groove 2O (Fig. 5) formed in the wall of the cylindrical casing 16, so that when the holder is pushed longitudinally of the casing in one direction by the end of the cue being inserted in the hemispherical depression 11 and pushed longitudinally of the casing, said holder 8 is simultaneously rotated by the pin 19 and groove 20.

A hollow cylindrical cap 21 encircles theV front end of the casing 16 and is prevented from being accidentally removed from said casing by a pin 22 fast to said casing and projecting into a right angle groove 23 in the cap, the pin being shown in dotted lines At the forward end in Fig. 6 in that portion of the groove which it occupies wh-en the cap is locked to the casing. `Vhen it is desired to remove the cap from the casing, said cap is turned to bring the pin into alinement with the longitudinal portion of the slot and the cap can then be withdrawn from the casing, the old piece of chalk removed from the holder and a new piece of chalk inserted therein.

The casing 16 is encircled by a band 24 having an ear 25 thereon, said ear being provided with a series of radial teeth 26 which project into a like series of teeth 27 provided upon the inner faces of ears 28, 28 on the bracket 29, said bracket having a base-plate 30 adapted to be fastened by screws to a suitable support, such as the wall of a room.

A clamp-bolt 31 extends through the ears 25 and 28 and by tightening the clamp-nut 32 the ears 2S are clamped to the ear 25, the teeth 2G and 27 meshing into each other and preventing said ear from rotating upon the stud 31 or upon the bracket 29, so that the casing 16 which is, in effect, in one piece with the band 24 and ear 25, may be set at different angles and clamped at any desired angle in a stationary position for use. In some cases it is desirable to place the bracket at a greater distance from the floor than in others. For instance, in Fig. 1 the bracket is illustrated as set at an angle such as would be desirable if the bracket were placed about six feet from the floor. On the other hand, if it were more convenient to place the bracket about three feet six inches from the floor, then the casing could be tipped to a horizontal position and locked in position by the clamp-nut 32 and bolt 3l.

In Fig. 5 it will be noted that a cubical block of chalk 10 is illustrated in position in the holder 8, said holder having four right angle grooves 33, 33 therein to receive the corners of the chalk when the cubical block is utilized, so that the holder, as seen by reference to Figs. 4 and 5, is adapted to hold either a cylindrical block or a cubical block.

The general operation of the device hereinbefore specifically and to some extent, in general, described, is as follows: Assuming the device to be set in the position illustrated in Fig. 1, the tip of the cue is inserted in the depression 11 and the user pushes upon the cue, compressing the spring 17 and moving the holder 8, together with the block of chalk 1() therein, longitudinally of said casing. At the same time a rotary movement is given to the holder and the chalk carried thereby by means of the pin 19 and helical groove 20. Upon releasing the pressure upon the cue, the spring 17 moves the chalk holder and the chalk back to the position illustrated in Fig. 1, the cap 21 serving as a stop to arrest the forward movement of the holder and chalk when the parts arrive in the position illustrated in Fig. 1. Upon this return movement, it is evident that the chalk holder and the chalk therein will be rotated in the opposite direction to that in which they were rotated during the rearward movement, and thus the chalk will be rotated in one direction and then in the opposite direction upon the tip of the billiard cue during one movement in and out of the cue.

It is evident that if desired, the user may push the chalk and holder backwardly as many times as desired, but once is suiiicient for all practical purposes.

Having thus described our inventiomwhat we claim and desire by Letters Patent to secure is:

1. A device for chalking cue tips having, in combination, a holder adapted to receive a block of chalk and means attached to said chalk whereby the same may be removed from said holder.

2. A device for chalking cue tips having, in combination, a holder adapted to receive a block of chalk and a strip of metal extending across the bottom of said holder with a prong adapted to project into said chalk, said strip extending along a groove in the inner face of the side wall of said holder and thence at an angle thereto at the outer end of said holder, whereby said chalk may be removed from said holder.

3. In a device for chalking cue tips a holder having a cylindrical recess therein with four right angled grooves in the wall of said recess extending longitudinally thereof, whereby said holder is adapted to hold either a cylindrical block or a cubical block of chalk.

4. In a device for chalking cue tips a holder having a cylindrical recess therein with four right angled grooves in the wall of said recess and extending longitudinally thereof, whereby said holder is adapted to hold either a cylindrical block or a cubical block of chalk and means attached to said chalk, .whereby the same may be removed from said holder.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
